Hi!
I think we may want to stick to our is-a mantra.I'm not sure I understand what you mean here. But our principle was to allow things that do not violate the LSP - such as adding optional parameters, for example. I think returning by-ref can be allowed on the same principle. Is there any problem with allowing it that you see? -- Stanislav Malyshev, Zend Software Architect stas@zend.com http://www.zend.com/ (408)253-8829 MSN: stas@zend.com
